Hello,

Well as far as I know, if your SA instance restart after sa-update, it
should find the most recent and up to date ruleset.

Did you restart your instance? if you use amavis, restart it as well.

You may want to remove the ancient (theoritacally unsued) rulesets in
/var/lib/spamassassin in order to keep the most up to date one.

If this do not work, review your configuration. I don't know, maybe
/var/lib/spamassassin/3.003001 is hardcoded somewhere?

This tends to proove that you do not sa-update your installation.

$ grep -r HK_LOTTO /usr/share/spamassassin/
/usr/share/spamassassin/50_scores.cf:score HK_LOTTO 3.599 2.755 2.993 3.599

You may either use sa-update (score is lowered to 1) or override the
score in your personnal ruleset.

Run sa-update and review your local scoring. Your system scored 3.6 points 
for HK_LOTTO alone, but the last published score was:

OK I've exported 294 UK National Lottery hams that have hit HK_LOTTO
to a mbox. However this is on a W7 client machine that doesn't have
rsync as far as I can tell.

You could just provide "a few dozen samples of these hammy msgs" via
masscheck.  The more you can provide, and the more representative it is,
the better.

Not including high scoring spam isn't a big problem.  Things spamassassin
gets wrong are most useful.

The automated score generation used for the sa-updates comes from email
from about fourteen people, so anything you can provide would probably
be beneficial.

At the bottom of that page is an "UploadedCorpora" link which you can use
to upload the emails themselves without even needing to run masscheck
yourself.

Yes.  But two of the developers have agreed that's worth changing, so it
could happen today....

And that could change the scores in either direction.

They're talking about automated score generation.  Currently, apparently,
the scores for this rule are fixed, and not included in the calculation of
ideal scores.  They're talking about including it in the calculation of
ideal scores.  Which you download the results of from sa-update.

They're not talking about local score modification.

score HK_LOTTO 0

50_scores.cf would be continually getting overwritten by updates, would

should this score be in hardwired in 50_scores.cf ?

The rule under discussion is HK_LOTTO which is defined in

Why are you claiming that it has no bearing on SA?

In general, there are rules that CAN'T help hitting some ham which is 
why a rule is used in a scoring framework to determine the overall score.

However, it seems that your configuration is using rules outside the 
project (which I author) and that has no bearing on SA.

Additionally, it appears your configuration is scoring the rules higher 
than it should at this time.

So most likely, AXB is correct and the proper solution is to amend the 
scores as the rules continue to be prevalent in Spam.

I'll just add that I can also confirm HK_LOTTO and HK_LOTTO_NAME 
(currently scoring 3.599 and 0.998) regularly hit UK National Lottery 
emails as well as UK Health Lottery emails.

I previously contacted Emailvision who is the ESP for the UK Health 
Lottery to advise them their emails were scoring very heavily in SA and 
recommend they maybe pre-screen outgoing emails with SA before sending 
(they were being flagged as spam at default scores).

I've been working around the high scoring HK_LOTTO rules by whitelisting 
with SPF. Here is what I have for the UK Health Lottery:

whitelist_from_spf	*@healthlottery.co.uk
whitelist_from_spf	*@*.healthlottery.co.uk
whitelist_from_spf	*@health-lot.cccampaigns.com

I haven't seen high/abusive levels of mail from these domains so 
consider whitelisting safe practice.

or maybe you just lower the score for your setup.

and rethink

required=4.5

or:
if you provide a few dozen samples of these hammy msgs , they can be 
included in the SA ham corpus
or:
you can directly contribute to rescoring by running a masscheck instance 
as per:

Last external rdns =~ /mailcontrol\.com/

Unless we think that the UK lottery's mail provider will also be
sending lottery spam?

Unfortunately there doesn't appear to be a really reliable way to do that. 
There was neither valid SPF nor valid DKIM on that message that would 
allow the lottery domain in the from or received headers to be trusted.

I suppose the rules could look for the UK lottery domain in the external 
received list and not fire, or reduce the score, but that's trivially 
subject to forgery.

Not a good score for ham :)

But it isn't... maybe 2 rules need amending so they don't hit genuine
UK national lottery ham.

Your message scored a 7.1 on my system. All the same rules hit except I 
don't use AWL which subtracted 2.1 on your system. I also use the KAM 
ruleset which added another half point.
